Given numbers are 656, 821, 398, 332

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(656, 821) = 538576

GCD(656, 821) = ( 656 x 821 ) / 538576

= 656 / 821

= 656

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

So, Greatest Common Divisor of 656, 821, 398, 332 is 1
